1>Textile dyeing and Finishing;2.>Printed Circuit Board Fluxes;3.>Laundry Sours

4>Leather Dyeing and Tanning;6>Industrial Chemical Manufacturing ;7>Electro polishing

  1. Function in cosmetic field grade

Glycolic acid, because of the small size of its molecules, can easily penetrate the skin. It helps loosen the bonds that hold skin cells together, allowing dead skin cells to slough off more effectively. The skin feels softer and smoother, and its overall appearance is enhanced.

  1. >It can remove the dead cells on the skin and can also be used as depilatory.

2> Can used for cosmetic material alpha hydroxy acid production.

3>.Moisturizing skin care.
4> Prevent and repair of skin cell damage.
5> Nourish skin, delay skin aging.
6>Good lubricity and smooth the skin.
